Eureka Springs is great for tourism. You could also go to NWA as they have had a lot of growth there and a lot of folks like to visit Crystal Bridges. Do not go to Harrison, that place is not welcoming is really the heel of Arkansas. If you like the outdoors and camping there are tons of places to go such as Petite Jean, Devils Den, Mount Magazine, etc. There is also the Crater of Diamonds if you want to try and dig for diamonds.

Nothing unless you like lakes and mountains.
